Bridgewire resistance test results shall be recorded in ohms and provided in the

Technical Report -Test Data Pack.

3.4.3 The insulation resistance test shall be conducted on the units in accordance with Table 1 and ATP TP-93670-04. Photographs shall be taken of the test setup with a unit.

Insulation resistance test results shall be recorded in ohms and provided in the Technical

Report -Test Data Pack.

3.4.4 The electrostatic discharge (ESD) test shall be conducted on the units in accordance with

Table 1 and ATP TP-93670-04. Photographs shall be taken of the test setup with a unit.

Electrostatic discharge test results shall be provided in the Technical Report -Test Data

Pack.

3.4.5 The radiographic examination shall be conducted on the units in accordance with Table 1 and ATP TP-93670-04. Radiographic inspection report and a digital or film copy of x-rays shall be provided with the Technical Report -Test Data Pack.

3.4.6 The no-fire test shall be conducted on the units in accordance with Table 1 and ATP TP-

93670-04. Photographs shall be taken of the test setup with a unit. No-fire test results including no-fire calibration and tester operation screen(s) shall be provided in the

Technical Report -Test Data Pack.

3.5 Functional Testing. Testing shall be performed in accordance with Table 1 and ATP TP-

93670-04. All test data and inspection results shall be recorded and provided in the

Technical Report -Test Data Pack. (CDRL A002)
